Why the other options are wrong:

• a federal policy change on emissions.: The report does not discuss any federal policy change on emissions.
• a global climate conference in Vancouver.: This was an award ceremony, not a climate conference.
• new factory regulations in British Columbia.: The report is not about factory regulations in British Columbia.

Correct Answer: a pilot at facilities in Alberta and Ontario.

Why this is correct: The report says the technology's results were verified during an eighteen-month pilot at facilities in Alberta and Ontario. This real-world testing proved the system works.

Why the other options are wrong:

• laboratory tests at a Vancouver university.: No university lab tests in Vancouver are mentioned.
• computer simulations reviewed by the jury.: The report says the results came from a real pilot, not computer simulations.
• a brief trial at a single factory site.: The pilot ran at multiple facilities for eighteen months - it was not a brief single-site trial.

Correct Answer: fits existing equipment at lower cost.

Why this is correct: The prize jury said the system stood out because it can be retrofitted to existing equipment at a lower cost than traditional carbon-capture plants. This means it fits what factories already have.

Why the other options are wrong:

• eliminates emissions from large power plants.: The system is for mid-sized factories, not large power plants, and it reduces emissions by forty-two percent rather than eliminating them.
• was funded solely by private investors.: The federal government partially funded the pilot - it was not funded solely by private investors.
• was developed at a Vancouver university.: The inventor is a Calgary-based engineer. The report does not identify a Vancouver university as the institution where the system was developed.

Correct Answer: in March twenty twenty-seven.

Why this is correct: The report says a full performance review of the technology is scheduled for March 2027.

Why the other options are wrong:

• once the Vancouver centre opens.: The planned production centre is in British Columbia; the report does not name Vancouver as its location. The review date is stated separately as March 2027, without linking it to the centre opening.
• by the end of this year.: The report says the review is in March 2027, not by the end of this year.
• after provincial regulations are approved.: The review has a set date: March 2027. The report does not state that provincial regulations must be approved before that review.

Correct Answer: cautiously optimistic despite practical challenges.

Why this is correct: The report celebrates the win and talks about new jobs and scaling up. But it also notes that widespread adoption depends on regulations and industry buy-in. This mix of good news and real challenges makes the tone cautiously optimistic.

Why the other options are wrong:

• sceptical about success beyond Canada.: The report does not express doubt about success beyond Canada.
• celebratory and certain about rapid adoption.: The report is positive but does not present rapid adoption as certain - it mentions obstacles.
• critical of government involvement.: The government is shown supporting the project, not being criticised.
